China civil aircraft airworthiness provisions have defined on the ozone concentration in the cabin. According to requirements of civil aviation airworthiness provisions, the study of aircraft cabin ozone concentration’s measurement results which was the ifrst in China had been done. According to the design index, conifguration and service conditions of airplanes, corresponding lfight test method was made and lfight test in Chinese high latitude area was completed, then cabin ozone concentration measurement data was analyzed. The results show that the aircraft cabin ozone concentration meets the requirements of civil aviation regulations.%民用飞机适航条款中对座舱内臭氧浓度有明确规定。依据中国民航适航条款要求，开展了我国首次民用飞机座舱臭氧浓度测量试飞研究。针对飞机的设计指标、构型及使用情况，制定相应的试飞方法，在我国高纬度地区开展飞行试验，进行座舱臭氧浓度测量分析，试验结果表明该飞机座舱臭氧浓度符合民航规章要求。
